From 30159aea4b3f6421da9d74a8bf22aad6d3bf26b4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=B6rg=20Krause?= Date: Mon, 4 Apr 2016 20:48:43 +0200 Subject: [PATCH] GNU version of strerror_r not available on musl The GNU version of glibc' `strerror_r` is non-portable. When the POSIX and GNU API collides musl always provides the POSIX API. That being the case for `strerror_r` musl does only support the POSIX version, despite of `_GNU_SOURCE`. --- Foundation/src/Error.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/Foundation/src/Error.cpp b/Foundation/src/Error.cpp index 6a8afb705f..00991fc0be 100644 --- a/Foundation/src/Error.cpp +++ b/Foundation/src/Error.cpp @@ -69,7 +69,10 @@ namespace Poco { without -D_GNU_SOURCE is needed, otherwise the GNU version is preferred. */ -#if defined _GNU_SOURCE && !POCO_ANDROID + /* The GNU version of strerror_r is non-portable and not + available on the musl C library. + */ +#if (defined __GLIBC__ || defined __UCLIBC__) && defined _GNU_SOURCE && !POCO_ANDROID char errmsg[256] = ""; return std::string(strerror_r(errorCode, errmsg, 256)); #elif (_XOPEN_SOURCE >= 600) || POCO_ANDROID
